I can almost predict when the weather changes, I will get a migraine. Being out in the sun can even throw me into a migraine. I Need to wear a hat when it is sunny outside.

I get the bad ones the day before a bad storm hits

I get them very often when barometric pressure changes. They start late in the day before the pressure moved in and they are killers! Pain in left eye, temple throbbing, jaw spasms and extra tight at base of neck. Light and sound sensitivity, hyper smelling is awful and really bad nausea. Lasts for most of the weather and then the migraine “hangover” causes me another lost day.

I have had weather related migraines for years. Any sudden change in the barometric pressure will usually trgger a major migraine. My mom also had them, and she became the 'weather lady' that everyone called before they scheduled a trip to the beach, amusement park, family reunions! If she had a migraine, it WOULD rain! I don't get them as severely as she did, but when I do, usually ice pack works for me. Also, I am prescribed Topamax as preventative that I take every day and Sumatriptn at first sign of a migraine coming on. And taking Alprazolam (generic for Xanax) for the anxiety I have due to migraines.
Hope this helps!

Mine usually occur with weather changes too. I know for me its a dark room and a nap and when I get up I can sort of function even though I am in a fog.
